Barbara Gordon was attending this party under protest. Attending the sort of party that Bruce Wayne threw was definitely not high on her list of things she liked to do, but Bruce just would not take no for an answer. Her protests about not having anything to wear resulted in him providing her with a dress, and a mask to go with it. He even sent a driver over to pick her up, so in the end, she ended up at the party after all.
That didn't mean she was going to enjoy herself, dammit. She was dressed in the shimmering green satin full length fishtail dress Bruce had sent over, which had been the perfect size, of course. Her mask was a glittering starfish affair, her long red hair loosely curled and spilling down over her shoulders. Green heels peeked out from underneath her skirt, and she'd tucked herself away in a corner where she could watch much of what was going on, but not be disturbed unless someone was really determined to find her. She was nursing a glass of champagne Alfred had brought her awhile back, smirking at a couple of people trying to drunkenly dance.
